DOUBLE HITCH.

Specification of Letters Patent.

Patented Jan. 29, 1913.

To all whom it may concern:

Be it known that I, HENRY B ULTHAUS, a citizen of the United States, residing at Byron, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Double Hitches, 01" which the following is a specification.

This invention relates to open links such as are used for repairing well chains, trace chains and the like.

One important object of the invention is improve the general construction of devices of this character.

A second important object of the invention is to provide an improved link of this character made from a single length of wire of uniform cross sectional area and shape throughout.

With the above and other objects in view, as will be hereinafter apparent the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing, like charactors of reference indicate like parts in the several views, and

Figure 1 is an elevation showing one face of a link constructed in accordance with this invention.

Fig. 2 is a similar elevation showing the opposite face.

Fig. 3 is a side view of such a link taken from the left side of Fig. 1.

Fig. 4c is a perspective view showing a modification of the link.

In carrying out the objects of the invention and, especially in the form shown in Figs. 1, 2, and 3 the link is constructed or a single length of wire or rod of uniform cross section and dimensions and this rod is so bent as to form a single convolution 10. One end of the wire is curved slightly inward in this form as at 11 while the remaining end of the wire is bent to extend diagonally across the convolution 10 as at 12 and is then' reversely bent in an arcuate curve 13 to conform to the shape of the link end and to lie in spaced parallel'relation to the convolution 10, this construction being best seen in Fig. 3.

Now, in connecting a chain with this form of the link it will be seen that one of the links of the chain is slipped over one end of the wire and carried around until it engages both parts of the wire at the link end and in like manner the link of the chain which it is desired to connect to the firstanentioned link of the chain is carried around until it engages both portions of the other end of this open link this being indicated in dotted lines in Fig. 3.

In the form of the invention shown in Fig. -ft the device is very similar to that previously described there being a single convolution 14- but in this case each end of the wire iscarried diagonally across what may be termed the body of the link as at 15 and the extremities are each reversely bent in an arcuate curve 16 coresponding to the curve 13 of the previous form. Thus the link in Fig. 4idiifers from Fig. 1 in having each end carried across the body and bent.

The form in Fig. l is used exactly as is the form in Figs. 1, 2, and 3.

There has thus been provided a simple and eflicient device of the kind described and for the purpose specified.

It is obvious that many minor changes may be made in the form and construction of the invention without departingfrom the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described but it is wished to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is 2-- An open link consisting of a single length of wire bent to form a single elongated convolution, one end of the wire being bent to lie diagonally across the convolution and reversely bent to follow the end of the c011- volution in spaced and substantially parallel relation thereto.

In testimony whereof I afliX my signature.

HENRY BULTHAUS.
